Images of the crash show one officer in a grassy area between two lanes on the highway, apparently in the process of sitting up. Another shot shows an officer lying down on the side of the road while receiving assistance.

Three of the four officers were taken to a local hospital to be treated for minor injuries and are in stable condition, White House press secretary Sarah Sanders said.

The injured officers were from the Westlake Police Department, Sulfur Police Department and the Calcasieu Parish Sheriff’s Office.

Motorcycle escorts stopped to deal with the accident, and some of them returned later to the motorcade, Reuters reported.

The accident did not impact the movement of Trump’s motorcade, Secret Service spokesman Mason Brayman said.

The motorcade continued on to the Cameron LNG Export Terminal in Hackberry, where Trump toured the facility. Later, he gave a speech promoting U.S. energy policy.
